Ultra Conformable Flashing Tape 3015UC Best Practices
Substrate Surface Requirements
3M
™
Ultra Conformable Flashing Tape 3015UC can be applied to
a wide variety of sheathing substrates, typically without priming.
Substrate condition is crucial to the adhesion performance of
any adhesive membrane.
• Substrate surfaces must be free of grease, oil, un-bonded
paint, corrosion or other substances that would adversely
aect the adhesive bond between the membrane
and substrate.
• Substrate surface must be dry to the touch for
optimum performance.
• Application temperature must be between 0ºF and 150ºF
(-18ºC and 66ºC).
• Service temperature from -40°F to 240°F (-40°C to 116°C).
• Rolls must be stored at a temperature between 0ºF and 150ºF
(-18ºC and 66ºC) to ensure initial bond performance.
Surface Preparation
• Fill gaps and cracks exceeding 1/8" width with 3M
™
Adhesive
Sealant 740UV, and tool the surface ush and smooth. Fill
gaps exceeding 1/2" width with closed cell foam backer rod or
a foam seal, then with 3M
™
Adhesive Sealant 740UV, and tool
the surface ush and smooth.
• Concrete substrates shall have ns ground ush and void
areas lled.
• Masonry substrates must have mortar joints struck ush.
Substrate Specic Guidelines
• Exterior gypsum sheathing shall have moisture content
below 19%, with no open joints or cracks wider than 1/2".
